Although not strictly a part of classic torque converter design, many automotive converters include a lock-up clutch to improve cruising power transmission efficiency and reduce heat. The application of the clutch locks the turbine to the impeller, causing all power transmission to be mechanical, thus eliminating losses associated with fluid drive.
The latter used an electronically controlled lock up torque converter. Applications: L4N71B. Applications: 1983–1984 Nissan Maxima; 1984–1988 Nissan 200SX;
Once fully locked, the torque converter no longer applies torque multiplication and will spin at the same speed as the engine. This provides a major increase in fuel economy. Modern designs provide partial lockup in lower gears to improve fuel economy further, but this can increase wear on the clutch components.
In 1995, the 4L60E received a PWM-controlled lockup converter. The early designs simple on or off lockup function while the later design can regulate the apply pressure as to not feel the lock up occur. GM added a fifth solenoid to the valve body, called the PWM solenoid. In 1996, GM introduced a redesigned 4L60E transmission case that ...
By historical context of comparison, the '50 Packard Ultramatic which was a torque converter applied two speed lock-up design with high and low range for four forward speeds and the '50 Studebaker/Detroit Gear featured a lock-up torque converter with three forward speeds. The lock-up feature of Packard's Ultramatic and Studebaker's DG 250 is ...
The 5G-Tronic (model W5A 330 and W5A 580 · type 722.6) is an electronically shifted 5-speed overdrive automatic transmission with torque converter lock-up (typically in gears 3, 4 and 5) and 2-speed for reverse.
